At grid cells where the calculated values are zero the wall boundary condition, case 2, is applied. +Each time @command{makeBoundary} runs it reads two input files and +produces one output file. The first input file, named +@file{topography.txt}, provides the height data. This file is also used +by @emph{FullSWOF} to define the domain topography. The file may be +saved in the current working directory or, alternatively, a symbolic +link to a file in an external directory may be created. To create such +a link use a command of the form: + +@example +ln -s /path/to/topography/file topography.txt +@end example + +The second input file is the @emph{boundary definition file}. This file +specifies the boundary type, the global discharge across the boundary +and the local gradient. Extra control parameters allow the global +discharge to be split across separate regions.
